Description

System and method for controlling smart device using remote controller
Technical Field
Embodiments of the present disclosure relate to a system including a smart board and a remote controller and a method for controlling such a system.
Background
Some smart boards are formed from interactive digital whiteboards. They may be connected to a computer and/or projector and may be controlled using a remote controller. An infrared receiving module is generally provided to receive infrared light emitted by a remote controller to control such devices.
The infrared receiving module is located in a front region of the apparatus or is mounted externally as a separate module. Due to the position of the receiving module, detection problems may occur, thereby reducing the controllability of such devices. Furthermore, the production of such a receiving module is expensive in different stages of the production of the smart device, such as the costs of the process, assembly, inventory, material supply, design and manufacturer rise. Most importantly, these modules increase the power consumption of the smart board and lead to additional costs.
Smart boards are commonly used in teaching and implement the following two main features. The first feature is to write on it and the second feature is to use as a computer screen that every student can see. When the board is connected to a computer and projector, a computer screen can be projected on the smart board by the projector. The smart pad can be turned on and off using the remote control, the user can switch between a "writing" mode and a "computer screen" mode, and while in the "computer screen" mode, the user can control settings, such as setting volume while watching video or entering a password by pressing a button on the remote control. Especially in this case the fast and efficient functionality of the system is suitable for continuous lectures. More information about an exemplary smart board according to the prior art is described in

Detailed Description
Reference will now be made in detail to the various embodiments of the disclosure, one or more examples of which are illustrated in the figures. In the following description of the drawings, like reference numerals refer to like parts. Generally, only the differences with respect to the respective embodiments are described. Each example is provided by way of explanation of the disclosure and is not meant as a limitation of the disclosure. Furthermore, features illustrated or described as part of one embodiment can be used on or in combination with other embodiments to yield yet a further embodiment. The description is intended to include such modifications and variations.
A common smart board may be controlled using a remote controller. These remote controllers typically operate based on IR standards. The smart board has an externally mounted module corresponding to the IR signal emitted by the remote controller to execute commands given via the remote controller. The external module can receive the IR signal emitted by the remote controller only when the remote controller is pointed at the module at an angle, and thus it is impossible to use the smart board quickly and efficiently. Furthermore, these externally mounted modules result in additional costs in production and use, thereby reducing the attractiveness of the use of smart boards.
Embodiments of the present disclosure overcome the above disadvantages by providing a system with multiple transmitters and multiple receivers such that a remote controller can point anywhere on the screen of a smart board and recognize signals transmitted by the remote controller wherever the remote controller points, without the need for an externally mounted module. Thereby ensuring a fast and efficient response and use of the smart board and reducing costs.
Fig. 1 shows a schematic diagram of a system 100 for controlling a smart board using a remote controller according to embodiments described herein.
